> Key: IGNITE-13189
> URL: https://issues.apache.org/jira/browse/IGNITE-13189
> Project: Ignite
> Issue Type: Sub-task
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Priority: Major
>
> As described in IEP-47 defragmentation is performed when a node enters a
> special mode called maintenance mode.
> Discussion on dev-list clarifies algorithm to enter maintenance mode:
> # Special key is written to local metastorage.
> # Node is restarted.
> # Node observes the key on startup and enters maintenance mode.
> Node should be fully-functioning in that mode but should not join the rest of
> the cluster and participate in any regular activity like handling cache
> operations.
